PATENT WHEELED SCRAPERi SPECIFICATION forming part of Letters Patent No.48,595, dated September 29, 1896.

Y Application iiled November 5, 1895. Serial No. 568,007. (No model.)

. a full, clear, and exact description.

Our invention relates to an improvement in wheeled scrapers, andespecially to an improvenient in the scraper for which Letters Patentwere granted to us November 2l, 1893, No. 509,278.

The object of the invention lis to provide a scraper in which the scoopwill be entirely under the control of one man, the manipulator beingalsocapable of driving the team attached to the machine, and to so simplifyand rearrange the parts of the machine that the entire machine will beunder better control of said operator than heretofore, and whereby alsothe scoop may be much more readily and effectually carried to thedumping position or restored to the working position.

Thel invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, foriningapart ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Fig. 4 is a partly sectional rear elevationtaken substantially on a vertical plane coin? cident with the axle ofthe machine. Fig. 5 is a detail view of the right-hand disk, adapted asone of the supports for the scoop and likewise adapted as alocking-disk. Fig. 6 is a plan view of the draft-pole sheath and aportion of the pole of the machine. Fig. 7 is a longitudinal verticalsection taken substantially on the line 7 7 of Fig. 6. Fig. 8 is atransverse sectional view through the axle, illustrating the connectionwith said axle of the rear port-ion of the scoop whereby the same may bereadily elevated. Fig. 9 is a detail view of one of the bearings of theshifting shaft; and Fig. l0 is a side elevation of the pole of themachine, illustrating the connection therewith of the draft device.

In carrying out the invention the ground or traction wheels l0 areloosely mounted upon an axle Il, and the inner face of the hub of eachground-wheel is provided with an attached ring or band 12, havingclutchteeth upon its inner face. Adjacent to the clutch-face of eachtraction-wheel a disk A is splined on the aforesaid axle, and eachlocking-disk comprises a cupped body 14, the body portions being carriedover the clutchrings l2 of the wheels, so as to exclude dust therefrom',and also a flange l5, which is located at the peripheral portions of theinner face of the body. This flange is preferably made wider at one sidethan the other, as illustrated particularly in Fig. 5, and the left-handdisk is adapted particularly as a locking-disk, having a pocket 17 madein the lower portions of the wider section of its iiange, a shoulder 16being formed at the -upper portion of the said iiange, as is likewisebest shown in Fig. 5.

At each side of the longitudinal center of the axle a shifting sleeve 18is mounted to slide upon the said axle and turn therewith.

Each shifting sleeve is provided at its outer face with a iiange 19,andbolts 20 are attached to the iianges of the said sleeves and are passedoutwardly through openings made in the body portions of the disks A, andwithin the body portion of each disk a clutch-ring2l is loosely mounted,and the said clutch-rings are secured to the bolts 20, as isparticularly shown in Fig. 4, the clutch-rings of the shifting sleevesbeing adapted for engagement with the clutch-surfaces of the Wheels,although they are normally held out of such engagement. Lugs 2la areproduced in the body of each disk A, being adapted for engagement withlugs 2l", made upon the peripheries of the clutch-rings 21, in order torelieve the pressure upon the bolts 20, as shown in Fig. 4;.

The frame of the machine may be said -to. comprise the yoke-section B.This yoke-section is .loosely mounted upon the axle, as shown in Fig. 4,the mounting occurring adjacent to the inner faces of the shiftingsleeves IOO y 1S, and in addition to the yoke B the frame comprises ahorizontal and longitudinal extension B of the yoke, located over thecentral portion of the machine, being carried in a forwardly direction.

The extension B is hollow and its inner surface is so constructed as toform a slideway 2l, as is best shown in Figs. G and 7, for the receptionof a slide 23. In the upper surface of the extension B of the frame ahorizontal slot 2l is made, extending from the front to the rear, andthe forward portion of the extension of the frame is in a measure closedby a strap or yoke-bar 25, and adjacent to this bar a latch 2G is hingedupon one side of the frame extension, the said latch normally extendingover the top of the extension and engaging at its opposite side with akeeper 27, as shown in Figs. 2, (l, and 7, and normally the slide 23,contained within the frame, is prevented from moving at predeterminedperiods by reason of a stop 28, formed upon the upper forward portion ofthe slide, engaging with the latch 2t. The latch 26 at its pivot end isprovided with an extension 2U", shaped in such manner as to receive thefoot of the operator, and the keeper 27 is of angular construction, asshown in Fig. 7, comprising a vertical and a horizontal member, thehorizontal member serving to limit the upward movement of the latch, andthe said upward movement will be such as to permit of the passage of thestop 28 of the slide beneath the latch and likewise the passage of akeeper. 2S, which is secured to and extends forwardly from a post orupright 29, located upon the rear portion of the slide, as is shown inFigs. 6 and 7.

It will be understood that the slide 23 consists of two parallel bars,as shown in Fig. G. rlhe forward or yoke-bar 25 of the extensionframe ishigher than the latch when at its full upper position.

If in practice it is found desirable, frictionrollers may be placed atvarious points in the slide, so as to facilitate the travel of thelatter in the extension of the frame, and this extension may be termed asheath for the slide. The pole is secured to the forward end of theslide 23 in anyV suitable or approved manner.

The clutches adapted for engagement with the hub-sections of thesupporting-wheels are operated through the medium of a shaft 31,encircled and controlled by a spring 3l, which shaft is journaled inbearings 32 and 2523, secured to the under face of the extension of theframe, and one of the bearings is illustrated in detail in Fig. 9, inwhich it will be seen that the opening 3l through which the shaft ispassed is slightly elongated. The rear bracket or bearing 33 is longerthan the forward bracket. Therefore the shaft has a rearward anddownward inclination, and the aforesaid shaft is rocked either throughthe medium of a foot-lever 35 (shown best in Fig.

l) or a hand-lever 3G, the hand-lever being at the left-hand side, andthese two levers may be continuous, if in practice it is founddesirable. Both of these levers, however, as is likewise the latch atthe front of the extension-frame, are within convenient reach from thedrivers seat 37, the said seat being supported on a suitable standard38, attached to the rear portion of the frame, usually the rearbow-section B thereof.

The shifting shaft 3l carries at its rear end a disk 39, firmly securedthereto, and two arms and l-l are pivotally connected with the said diskat diametrically opposite poin ts and the arms extend in oppositedirections, one to an engagement with each of the shifting sleeves 1S.rlhe opening 34 in the lower hanger or bracket 33 of the shifting shaftpermits the shifting arms to be so operated that a single clutch may bebrought in to action at a time and be slid into connection with atraction-wheel l0.

A scoop C is supported at its sides by attaching to these facesupwardly-extending arms 42, and these arm s are pivotal] y attached tothe disks A at the lower portion of the enlargement of their flanges 15,preferablyj ust below the pocket 17 on the right-hand disk and at acorresponding point on the left-hand disk, so that when the axle isrevolved the disks are turned also, and the scoop will be carried upwardor downward according to the direction in which the axle is turned. Thescoop is locked in an upper or in a lower position by means of alocking-bolt 43, adapted for engagement with the shoulder 16 of theleft-hand or locking disk when the scoop is in its lower or workingposition, as shown in Fig. i, and this bolt will enter the pocket 17 ofthis disk when the scoop is raised, holding it in such position. Thislatch, as illustrated in Fig. 2, is preferably provided with abifurcatedrear section, and at its bifurcated point is pivoted to a rear uprighttl-n of a substantially U bracket 14, secured upon the lefthand portionof the rear frame-section B, the forward member 4:41 of this bracketbeing adapted as a guide for the bolt, and the bolt is operated throughthe medium of a lever 45, which is preferably fulerumed in thebifurcated portion thereof and is curved at its lower edge to bear uponthe plane or bottom surface of the bracket -i-i.

The scoop is dumped after being raised to an upper position by theaction of the slide 23, the said slide being carried forward by themovement of the beam when the latch 2G is opened up. The attachmentbetween the slide and the scoop is shown in Figs. l, 2, and 8, as islikewise the attachment between the axle and the rear of the scoop, thelatter attachment being for the purpose of so inclining the scoop as toinsure all of the material being emptied therefrom.

rlhe scoop is provided at the rear with an upwardly and rearwardlyextending ear 4G,

IIO

and this ear is pivoted in an elongated slot 47, which is made in therear end of the horizontal member of a substantially T-shaped arm D, andthe forward end of the said member is upwardly curved and pivotallyconnected with a crank-arm 48, secured, preferably, upon the centralportion of the axle 11, as shown in Fig. 8. The upper end of thevertical member of the said T-arm D is pivoted between the rearextremities of two links 49, these links being pivoted at their forwardends to the. rear upright 29 on the slide 23. Stirrups 50 are preferablysecured to the forward portion of the frame extension to receive. thefeet of the driver.

In order to facilitate the draft, an attachment is provided to the pole30, (shown in Fig. 10,) whereby the draft will be obtained from the rearend portion of the pole, and to that end a link 51 is placed beneath thepole and is pivotally connected to a fixed clevis 52 at the heel of thepole; and the said link 51 is led beyond the forward extremity of thepole through a guide 53, being provided at the said forward end withmeans for attachment to a whifiietree.

The operation of the machine is substantially as follows: Taking it forgranted that the scoop is in an upper position, in which event thelocking-bolt 43 will be in the pocket 17 of the lockingdisk A, when itis desired to drop the scoopl to scrape the road this is accomplished bydrawing the lever inward,

thereby carrying the bolt 43 out of engagement with the said disk, andthe scoop by reason of its weight will drop to the ground after thelatch 26 has been raised to release the rear catch 28 of the slide fromengagement with it. After the scoop has dropped to the ground and as thehorses are driven forward a predetermined distance, the bolt being thenin engagement with the shoulder 16 through the medium of the lever 35 or36, which may be operated by foot or by hand, the clutches on the axlewill be brought into action and engage with the clutch-faces of thefriction-wheels, therefore revolving said axle and causing the attacheddisks A to be carried upward, and they will carry with them the scoop.The scoop will continue to be raised until the locking-bolt 43 will haveentered tlie pocket 17 of the left-hand lockingdisk,whereupon theclutches are carried out of engagement with the friction-wheels, itbeing understoodthat the clutches can be operated either by the hand orthe foot lever, the spring 31a upon the shaft 31 releasing them when thepressure is relieved. The scoop being in its upper position, when thedumpingground is reached, thedriver will raise the latch 26, and thehorses, drawing forward, will carry the slide with them, thereby tiltingthe scoop upon its pivotal support and causing the load to dump, thecrank connection of the rear supporting-arm of the scoop with the axlebeing such that when the scoop is tilted it will assume a position ofsteep inclination. When the slide has been carried forward to the fullextent of dumping the scoop, the latch 28a will have passed and becomepositively engaged with the latch 26, the said latch having beenpermitted to drop and hold the scoop in its dumping position. In orderto carry the scoop downward again to'the ground, the latch 26 is raisedand the lockingbolt is disengaged from the left-hand disk by theoperation of a hand-lever 45, and the weight of the scoop will carry itto its lower position. This return of the scoop may be aided, ifnecessary, by a backing of the horses. The object of the crank-and-leverconnection between the axle and rear end of the scoop is to provide apivotal mounting for the arm D, so that it may swing upwardly at itsrear end in the manner above described. As thewaxle rocks, the crank-armwill swing and carry the arm D in a corresponding manner clear of theground under all conditions.
